AI Technical Summary

Benefits of technology

[0015]The present invention is based in part on the discovery that impregnating a disposable substrate with a certain cleaning composition unexpectedly improves the cleaning efficacy of the substrate and prevents ultraviolet light induced degradation of the leather surface.

Problems solved by technology

Liquid cleaners have limited cleaning efficiency with respect to particular types of soils, and are subject to streaking or redepositing of soil onto the leather surface.

Preparation of Premoistened Disposable Substrate (Wipes)

[0269]The formulations prepared in Example 1 are then applied to spunlace non-woven wipes. Each of the test solutions are spray applied to the lightweight fabric (spunlace non-woven supplied by AFG Wipes Inc.) with about 6 grams of solution added to about a 2 gram fabric swatch. Therefore, the loading on each wipe is about 300% based on initial dry weight of the untreated wipe.

Application of Wipes on Leather Samples

[0270]Wipes are applied to the leather using a Gardener Scrub Tester in the following manner.[0271]1. Leather samples (Brown NuBuck Leather) are placed on a Gardener Scrub[0272]2. The cellulose sponges are wrapped with saran wrap and placed in the holder[0273]3. The treated wipe is placed around the sponge in the holder[0274]4. Gardner machine is set for four cycles[0275]5. The sponge passes over the leather for four cycles[0276]6. Measure sample

Abstract

The present invention is directed to a premoistened, disposable, cleaning substrate to improve dirt pick-up and to retard redeposition of the dirt back onto the cleaned leather surface. The said substrate is incorporated therein with a cleaning composition to improve cleaning and impart protection and/or preservation of the leather surface or article. The said substrate is further incorporated therein with UV absorbers to further protect the leather surface, improve appearance and durability. The impregnated substrate can be employed to clean leather surfaces such as furniture, clothing, shoes, belts, automobile upholstery and the like. In addition, a method of preserving a leather surface or article by contacting said surface with said substrate is disclosed.
